The 2015 ESPYs were an emotional affair. In addition to Caitlyn Jenner accepting The Arthur Ashe Courage Award and delivering a powerful speech about her transition, we also saw Cincinnati Bengals player, Devon Still, open up about his daughter's battle with cancer. There were a few lighter moments as well, including host Joel McHale taking jabs at Bill Cosby and UFC champ Ronda Rousey aiming at Floyd Mayweather. Take a look at the highlights below.

Devon Still's Emotional Speech About His Daughter

Cincinnati Bengals defensive tackle Devon Still accepted the Jimmy V Award for Perseverance, and gave a lengthy and emotional speech about his daughter Leah Still's ongoing battle to beat cancer, the career sacrifices he made to be with her, and how much she inspires him. He ended the speech with a video of adorable Leah thanking everyone for their support.

LeBron Sarcastically Accepted His "Second Place" Award

LeBron James seemed to be confused when he won the trophy for "Best Championship Performance," since his Cleveland Cavaliers lost to the Golden State Warriors in the 2015 NBA Finals. “Second place got me this. This wasn’t expected at all," he told the audience, later adding, “I’ll take this second place award and take it to my house." Viewers at home thought that Triple Crown winner, American Pharoah, deserved the honor.

Joel McHale Went After Bill Cosby

During his opening monologue, Joel McHale let the insults fly. Tiger Woods and FIFA President, Sepp Blatter, weren't spared and neither was Bill Cosby. He congratulated UFC champ Ronda Rousey on her success, by declaring that "Ronda’s knocked out more women than Bill Cosby." No worries though -- he apologized. "Oh, you know what? I’m sorry," he told the audience. "I misspoke. I meant Dr. Bill Cosby."

Ronda Rousey Took A Shot At Floyd Mayweather

After beating out Floyd Mayweather for the Best Fighter Award, the UFC Champ had some pointed words for her fellow nominee, who has been accused of committing domestic violence in the past. "I wonder how Floyd feels being beat by a woman for once," she said during a red carpet interview.
